You can put this solution on YOUR website! Jimmy has seven times as many dimes as nickels. Their value is $3.75. How many nickels does he have?
-----
Equations:
d = 7n
10d + 5n = 375
-------------------
Substitute for "d" and solve for "n":
10(7n) + 5n = 375
70n + 5n = 375
75n = 375
n = 5 (# of nickels)
=======================
d = 7n*7*5 = 35 (# of dimes)
=============================
